To all whom it may concern:

Be it known that I, TADIUS wloz, a citizen of the United States, and aresident of Ghica o Heights, county of Cook, and State 0 Illinois, haveinventedcertain new vand useful Improvements in AutomaticFire-Extinguisher S stems, of

which the following is a clear, in l, and exact description.

My invention relates 'to automatic valves used in the dry-pipe system offire extinguisher apparatus. There has been difiicult-y in making thevalves used in these systerns watertight, and the valve seating meanshave not been made so that they would readily unlock and release thevalve. In the systems where an explosive has been used to release'thevalve, the explosive substance has not been placed ina receptacle whereitcan' be kept perfectly dry and so that it would retain its explosivequality,

The objects of my invention are to provide a valve which will avoid theabove objections and embody many other advantages and to provide meanswhich will 0 crate to release the interlocking devices ho ding the valvein place, regardless of atmospheric conditions or the time which mayelapse before the system is called into operation.

For the accomplishment of these and other objects, the inventionconsists in the novel details of construction hereinafter particularlydescribed, reference being had to the accomfpanying drawings forming apart hereo in which the same reference numerals designate likepartsthroughout the several views, and in which Figure 1 is a verticalsection of the automatic valve that normally closes the lateral serviceipe, and the releasing means for said valve ig. 2 is an elevationof..,the valve and Y attached parts Fig. 3 is'a detail of a fusible.plug.

Referring to the drawings, .a nipple 2 adapted to be attached to aservice pi e, is attached by means of flange 3 to the iii go 4 of valvecasin 5, suitable screws connecting the said anges. 'The valve chamberinclosed by the valve casing 5 is nearly cylindrical in shape and islarger in diameter, in its lower portion than the bore of the servicepipes connected with it. 4

6 is a metal circular 'disk connected to v V valve stem 8, and normallyrests on the annu- Ian valve seat 7 of tne casing and prevents the waterfrom service pipe connected at 1 from enterin into the pipe above thevalve J. STANKIE- chamber. T e base of the valve stem 6 is cone shapedand, fits snugly into" a cone shaped openin in thecaslng 5, when thevalve is ralsed y the water, thus revent-ing the water from leaking outaroun vthe valve stem. Normally the valve disk 6 is held to the valveseat 7, by means of a curved arm 9 I which. presses on the upper end ofsaid valve stem 8. Said curved arm 9 is pivoted on .a lug formed on theupper art 11, at a point .ad acent to where the va ve stem 8 extendsthrough the valve casing and slightly above the said stem when it restsnormally on the This arm 9 normally extends.

valve seat. horizontally from the casing and at right angles to it. Insaid arm is a set screw 10 which can be screwed through the said am anddown on the head of the valve stem 8.

Thisset screw when screwed down on said stem holds the valve 6 rigidlyupon its seat v so that water cannot esca e around the valve.

Normally the free end 0 the arm is engaged by notch 12 of lever 13. Thislever '13 is e bow shaped, is hinged to the valve casing and is soformed that the distance from its end 14 to the notch 12 is much greaterthan from notch to. the hinge end of the said arm.

A hook 16 is pivoted on the nipple 17. The

end 14 of the leverand the free end 15 of the hook are so formed thatthe hook will readily unlock from the said lever by which normally it isenga ed when in normal position. Hook-16. is s ightly curved and fromthe under side arm 18 extends downwardly. This arm at a point oppositethe recess 20. is circular and to the under side-of same is attached acircular piece of some-.non-conducting material, which fits snugly overthe end of the plug'or cartridge 21 in the mortar recess. 20. As thecover 19 is raised by the explosion of the explosive material in saidcartridge, the arm'18 is forced upward, the hook 15 unlocking from lever13 and the arm 18 striking. the latter forces it outward and the? arm' 91s disengaged from notch 12, and the arm 9 is then forced u ward by .thewater pressin against the'ya ve disk 6.

At one point t e valve casing has been thickened and tapped to admitplug 22 which when screwed out leaves the valve chamber exposed. 4 I

23 is'a cartridge made of glass or other suitable material in the form.of a capsule, throu h the cover of which fuses are extende and come intocontact with the explosive placed into said cartridge. The cover 24 isfitted over the mouth of the said cartridge and is hermetically sealed.This cartridge is placed in a cover 21 of non-conducting material whichin turn is placed into socket 20 on the nipple 17.

Having thus described my invention what I claim is 1. In an automaticfire extinguisher system, a valve casing having inlet and outletopeningsand a passagewaytherethrough, a

- valve mounted in said casing and adapted to close said outlet openingand having a stem projecting through said casing, an arm pivoted on-saidcasing and adapted to engage said valve stem, a lever pivoted on saidcasing and adapted to'hold said arm in operative position, a socket insaid casing, an explosive cartridge in said socket fuses in contact withthe explosive in said cartridge, a hook pivoted on' said casing adaptedto engage said lever, and to form a cover for saidsocket when the hookand lever are in operative position. 4

2. In an automatic fire extinguisher systerm, a valve casing havinginlet and outlet openings and a passageway therethrough, a valvecontrolling said'outlet opening, a stem on said valve projecting throughsaid casing, an arm, pivoted on sa1d casing, an adjust ing screw in saidarm adapted to engage sald valve stem, a lever pivoted on said cas-- ingadapted to interlock with said arm, a socket in said casing, an exlosive in said socket means in contact wit the explosive for operatingsame, a hook pivoted to the casing and adapted to engage said lever whenin operatlveposition, a cu shaped member attached to said hook, anadapted to form a cover for said socket, an arm on said hook adapted tostrike said lever when the explosive 1's ignited. a i

In testimony whereof, I have hereunto set.

my hand and 1908. A
